CYCLOMETER.

SPECIFICATION forming part of Letters Patent No. 508,941, dated November 21, 1893.

' Application filed December S, 1892. Serial No. 454,471. (No model.)

To a/ZZ whom it may concern:

Be it known that I, JOHN S. HILLIAED, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Oyclometers, of which the following is a specification.

The principal objects of my present invention are first, to provide a neat, compact, reliable, accurate and comparatively inexpensive cyclometer, `especially adapted for attachment to the frame-work of a bicycle, tricycle or other similar vehicle in such manner as to be always in plain view of the rider; second, to provide simple, adjustable and eficient means for imparting motion to a train of registering wheels of the instrument from apointin close proximity with the axle or hub of one of the wheels of the vehicle in such manner that the instrument is not subjected to undue shock or jar; and third, to provide the instrument with a train of registering wheels arranged and adapted for operation in such manner that accidental retrograde motion thereof is prevented. j

My invention consists of the improvements vin cyclometers hereinafter described and claimed.

The nature, characteristic features and scope of my invention willbe more fully understood from the following description taken in connection with the accompanying drawings forming part hereof; and in which- Figure 1 is a perspective view showing a cyclometer embodying features of my invention in application to the front wheel of a bicycle, tricycle or other similar vehicle. Figs. 2 and 3, are views partly in elevation and partly in section taken from the respective sides of the cyclometer. Fig. 4, is a section on the line 4 4, ofFigs. 2 and 3, showing the rocker-arm, ratchet-wheel and their accessories. Fig. 5, is a section on the line 5-5, of Figs. 2 and 3, showing the train of registering wheels and illustrating the application of a Geneva stop motion thereto; and Fig. 6, is a top or plan view of the dial-plate and its complemental ordinals, and with the housing removed.

Referring to the drawings the exterior housing of the cyclometer' is preferably circular in form and comprises two parts, whereof one a, is provided with a glass-plate or cover a', and the other a2, is provided with a lug a3, and its complemental nut and washer, whereby the device may be secured to position for use in a manner to be presently fully described.

b, is a base-plate provided with a centrally 4disposed journal bearing b', and with suitable internally threaded or tapped apertures b2, for the reception of screws, whereby the respective members a and a2, of the housing are held to place.

c, is a partition-plate connected with and carried above the base-plate b, by means of distance pieces c', and screws c2.

' d, is a dial-plate provided with Windows OZ', d2 and cl3, andwith a dial d4. This dial-plate d, is supported above the partition plate o, and beneath the glass cover a', by means of distance pieces d5 and screws d6.

e, is a ratchet-wheel carried upon an arbor e', journaled in the bearing b', and extending upward through an aperture in the partition plate o. The upper extremity of this arbor e', is provided with a linger f, located above the partition plate c.

e2, ,is a detent for preventing retrograde 8o movement of the ratchet-Wheel e.

g, is a rocker-arm loosely mounted upon the arbor e', and provided at or `near one extremity g thereof, with a spring controlled pawl g2, for engaging the respective teeth of the ratchet-wheel e.

s, is a spring connected at its respective extremities with the rocker-arm g, and with a post s', projecting upward from the base-plate t. The other extremity g3,of the rocker-arm 9o g, projects through a suitable slot in the exterior housingof the device and is provided with a roller g4, having a rubber or other elastic tread g5, adapted to collide with and run over a suitable projection on the vehicle IOO arm g, causes the spring-pawl g2, to advance the ratchet-wheel e, in the direction indicated by the arrow in Fig. et, a distance equal to the space between its respective teeth, with the result that the tingerf, is shifted in asimilar direction and at the same rate of speed.

h, is a registering spur-wheel revolubly mounted upon the partition plate c, and adapted to be driven by the finger f, in the direction indicated by the arrow in Fig. 5.

7L', is a detent for preventing retrograde motion of the wheel h.

The wheel h, is advanced by the tingerf, a distance equal to the space between its teeth for every revolution of the ratchet-wheel e, and is provided with a pointer or hand h2, that operates in connection with the dial Clt.

fzl, is a disk carried by the wheel h, and provided with a radial recess,trom the center of which a radial pin t', projects beyond the periphery of the disk.

j', is a registering-wheel revolubly mounted upon the partition-plate c, and provided with spacesjz, adapted to mesh with the pin.

t", and with concavitiesj, adapted to slide upon the periphery of the disk t', and to enter the radial recess therein, so that the wheel j', and disk Fconstitute a so-called Geneva stop movement, whereby the registering wheel j', is held against retrograde movement in such manner that it may be advanced in the direction indicated by the arrow in Fig. 5,through the intervention of the pin i', and oncefor each revolution of the wheel h. This wheelj', is provided with the numerals from O to 9 inclusive, visible through the opening d3, and with a disk j, similar inall respects to the disk z'.

t, is a registering-wheel precisely similar to the wheel j', and revolubly mounted upon the partition-plate c. This wheel 7c, is controlled by the disk j, and is driven in the direction indicated by the arrow in Fig. 5, for a distance equal to the space between its teeth by the pin jt, of the disk j, during each revolution of the latter. This wheel 7e, is provided with the numerals from Oto 9 inclusive, visible through the openings cl2, and with a disk k2, and pin 7c3, that drives the registering-wheel Z, in precisely the same manner as the disk j, drives the wheel 7c. This wheel Z, is provided with mumerals from 0 to 9 inclusive, disposed in such manner that they are visible through the opening d.

It may be remarked that the employment of the Geneva stop-movement for driving the registering-wheels j', k and l, prevents retrograde movement thereof and causes one complete revolution of one of them to ad Vance the next wheel in the series a distance equal. to the Space between its respective teeth. In the present instance each wheel has ten teeth and a corresponding number of numerals, so that a complete revolution of one wheel causes the next wheel of the series to be advanced a distance equal to one tenth l the pin 7c3,

of a revolution, whereby the succeeding numeral is caused to appear beneath the opening in the dial-plate d, as is hereinafter more fully explained.

My improved cyclometer may be applied to a bicycle by means of a bracket m, provided with slotted arms m and m2, whereof one of the arms m', engages the lug as, and the other m2, is clamped tothe nut m3, that serves to connect the one extremity of the axle with the biturcated or other head of the vehicle.

n, is a semi-circular crown-cam connected with the spokes o, of the wheel of the vehicle by means of a clamping-plate 0', and setscrews o2, and adapted to contact with the roller g4, and thus reciprocate or trip the arm g, once during each revolution of the vehicle wheel. It may be remarked in this connection that the slotted bracket m, permits of the adjustment of the cyclometer, and that the crown-cam n, and roller g4, not only prevent any undue shock from being imparted tothe rocker-arm g, but also permit of the machine being run in a reverse direction.

In practice the number of teeth of the ratchet-wheel e, will depend upon the diameter of the wheel of the vehicle, the object being to cause the ratchet wheel e., to be revolved through the instru mentality of the rockerarm g, crown-cam n, and spring s, once for each twelfth of a mile traversed by the vehicle. In the present instance, by reference to the drawings, it is to be assumed that the diameter of the vehicle wheel is thirty inches. Consequently the ratchet-wheel e, is provided with titty-six teeth. It alarger or smaller vehicle-wheel is employed a ratchet-wheel having a proportionately larger or smaller number of teeth must be employed. The ,spurwheel h, is provided with twelve teeth and consequently is advanced by the finger f, one tooth for each revolution of the ratchet-wheel e, and consequently one tooth for each twelfth of a mile traversed by the vehicle, and makes one complete revolution for each mile traversed thereby; and the pointer or hand h2,in dicates upon the dial d4, the distance traversed in twelfths, quarter and half miles. The wheel j, is provided with ten teeth disposed in alignment with the ordinals 0 to 9 inclusive, and is advanced by the pin t", one tooth for each revolution of the spur-wheel h,

thus causing a corresponding numeral to apt pear beneath the aperture d3, so that the wheel j', makes one complete revolution for every ten miles traversed by the vehicle. The wheel 70, and its ordinals are advanced a distance corresponding to one of its ten teeth by the pin jl, for every revolution of the wheel j', or for every ten miles traversed by the vehicle, so that the ordinals appearing beneath the aperture cl2, indicate the number of ten miles that have been traversed by the vehicle. The wheel Z, and its ordinals are advanced a distance corresponding to one of its ten teeth by for every revolution of the wheel 7s, so that the ordinals appearing beneath the aperture d', indicate the number of hundred miles that have been traversed by the vehicle. Thus the cyclometer registers the distance in miles and fractions thereof traversed by the vehicle up to one thousand miles, whereupon the registration proceeds anew for another thousand miles without any necessity of resetting the apparatus. The distance traversed less than a thousand miles may be readily ascertained by reading the ordinals that appear beneath the apertures d', d2 and d3, in the usual manner and then ascertaining the fractions of a mile traversed by reference to the dial d4, for example, the distance indicated by the cyclometer illustrated in Fig. 6, is one hundred and twenty-three and one-quarter miles.

In cases where a greater number of miles than one thousand is to be registered an additional Wheel or wheels provided with ordinais and arranged in the manner hereinbefore described may be employed, and this duplication of wheels, it will be readily understood, may be extended as required andV still be within the scope of my invention.

Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A cyclometer comprising a housing attached to the outer end of the axle, atrain of registering wheels, a centrally pivoted arm provided with a pawl foractuating said train of wheels, a crown cam carried by the spokes ofthe vehicle Wheel and adapted to rock said arm in one direction and a retractingV spring for rocking the arm in the other direction, substantially as and for the purposes set forth.

2. A cyclometer comprising a housing attached to the end of the axle of a vehicle wheel, a train of registering Wheels, a centrally pivoted arm provided at one extremity with a pawl for actuating said train of wheels and at the other extremity with a roller, a crown cam carried by the spokes of the vehicle wheel/and adapted to run under said roller and rock the arm in one direction, and a retracting spring for rocking the arm in the other direction, substantially as and for the purposes set forth.

3. A cyclometer comprising a housing, a bracket adj ustably attached to the axle of a vehicle and to the housing, a train of registering wheels, a centrally pivoted arm provided at one extremity With a pawl for actuating` said train of Wheels and at the other extremity with a roller, a crown cam adj ustably secured to the spokes of the vehicle Wheel by a clamping plate and screws and adapted `to run under said roller and rock the arm in one direction, and a retracting spring for rocking the arm in the other direction, substantially as and for the purposes set forth.
